Stone holding downstem end

ABSTRACT

The stone holding downstem end is a modification to a standard downstem end to enable it to hold a porous stone. A standard downstem end is a full circle and only allows the stone to be heated from above. By subtracting material from the receiving end of the downstem we create a new downstem end that is not receptive to a standard bowl anymore, but is instead specially modified to hold a porous stone. With the modification the user can heat the stone from the side rather from just above. This increases the potential for material to be vaporized and less chance for the material to melt through.

BACKGROUND OF INVENTION

Two methods of marijuana consumption are smoking and vaporization. Manytools are used in this process, such as pipes and waterpipes. Theprocessing of marijuana into concentrates has grown in popularity alongwith vaporization techniques to consume the concentrates. Classic pipesand waterpipes have bowls on one end where the dry herb marijuana isplaced for consumption. Waterpipes commonly have downstems that hold aremovable bowl. Marijuana concentrates cannot be heated in traditionalbowls because they will turn into liquid and run out of the bowl ratherthan vaporizing. Many modifications have been made to pipe and waterpipebowls to adapt for the use of concentrates. One modification is toreplace or fill the bowl with a porous stone and then place themarijuana concentrate on the stone. A waterpipes with a downstem andremovable bowl can be converted to hold a stone by simply removing thebowl and adding the stone to the downstem. Heat is then applied to themarijuana concentrate and the stone. The marijuana concentrate turnsinto a liquid and mostly retained in the stone due to its porous nature.This gives the concentrate a chance to turn into a vapor as the stone isheated. Since the stone is placed in the bowl or the downstem, heat hasto be applied from above. The result is the concentrate receives heatbefore the stone. This is a problem because the concentrate will not be100% captured in the stone and there will be an amount of waste. Thecurrent invention address this problem by making the stone accessable tobe heated prior to heating the concentrate.

SUMMARY

The invention is a new form of the bowl receiving end of a downstem fora waterpipe. A downstem is a pipe that extends from outside to insidethe waterpipe and down under the water contained within the waterpipe.The bowl receiving end of a downstem has a variety of standard forms andcan be attached to another pipe to make a completed downstem with theappropriate length for a given waterpipe. The invention will focus onthe bowl receiving end of a downstem and consist of a subtraction alongone edge of the bowl receiving end of a downstem pipe. The subtractedmaterial will enable the stone to be heated from multiple angles toinclude side angles, as opposed to only being able to be heated fromabove without the subtraction.

DETAILED DESCRIPTION OF HOW THE INVENTION WORKS

The invention is a new form of the bowl receiving end of a downstem fora waterpipe. The bowl receiving end of a downstem for a waterpipe iscommonly constructed independently and then attached to another simpletube to create the downstem. The method of attaching of these two piecestogether to create the downstem varies depending on the materials beingused. The current invention does not depend on the materials being usedor the method of attachment, but rather the change in form of the bowlreceiving end of a downstem to create increased utility in theconsumption process of marijuana concentrates.

Drawing 1 is an illustration of the invention with a partial lengthsubtraction 1. The subtraction depth 3 the and the subtraction arc 2describe the volume to be subtracted. The bottom end 11 has a standardfinish, dependent on materials used, such that it can be can be attachedto the corresponding tube material to form a complete downstem.

Drawing 2 is an illustration of the invention with a partial lengthsubtraction 1,4 fitted with a porous stone 5. The subtraction depth 3should be deep enough so that the porous stone 5 sits inside the bowlreceiving end of the downstem 1,4 and within the section containing thesubtraction while seeking to minimize the stone gap 6. The angle of thesubtraction arc 2 is important. The subtraction arc 2 must be less than180 degrees but greater than 0 degrees. A practicable angle for thesubtraction arc 2 would reside between 45 degrees and 60 degrees. Thesubtraction arc define how much of the porous stone 5 will be exposedfor heating from the side when added. The porous stone 5 is natural heldin position in the bowl receiving end of the downstem 1,4 with frictiondue to the diameter of the porous stone 5 and the diameter of the bowlreceiving end of the downstem 1,4. The bowl receiving end of thedownstem 1,4 can have either a constant diameter or a dynamic diameterwhere the receiving end has a larger diameter than the dispensing end.This means the invention should be constructed with a specific porousstone 5 diameter in mind, but a bowl receiving end with a dynamicdiameter will allow for more variance in the porous stone 5 diameter.

Drawing 3 is an illustration of bowl receiving end of the downstem witha full length subtraction 7. Since the bowl receiving end of thedownstem 1,4,7 needs to be attach to another tube at the bottom end11,12 to complete the downstem, it may be easier (depending on materialsand corresponding subtraction methods) to make the subtraction depth 3,8the entire length of the bowl receiving end of the downstem 1,4,7.Drawing 4 is an illustration of bowl receiving end of the downstem witha full length subtraction 7,9 fitted with a porous stone 5,10. Theporous stone 5,10 is again held in place by friction, but now there isno stone gap 6 to worry about. Instead of design at aiming to minimizingthe stone gap 6, the design should aim to set the stone near the bottomof the bowl receiving end of the downstem with a full length subtraction7,9.

An alternative form of the invention is to utilize more than onesubtractions to increase the range of angles that the stone maybe heatedfrom. When performing multiple subtractions each individual subtractionarcs must be less 180 degrees. Drawing 5 is an illustration of anexample of a stone holding downstem utilizing two subtractions 13.Drawing 6 is an illustration of an example of a stone holding downstemutilizing two subtractions 13,14 fitted with a porous stone 5,10,15.Drawing 7 is an illustration of an example of a stone holding downstemutilizing three subtractions 16. Drawing 8 is an illustration of anexample of a stone holding downstem utilizing three subtractions 16,17fitted with a porous stone 5,10,15,18.

The invention is the new form of the bowl receiving end of the downstem1,4,7,9. This form is reachable through subtractive methods applied tocurrent forms of bowl receiving ends of downstems. This form can also bereached by utilizing additive methods such as 3d-printing. Glass is apopular material for downstems. Standard glass bowl receiving ends ofdownstems can easily be modified using subtractive methods by a personskilled in the field of glass manufacturing to produce the invention,stone holding downstem end 1,4,7,9.
